Amiga/Lorraine Mugs
Every touristy place has them: Souvenirs with given names on them. If you have an uncommon name, or a friend with an uncommon name, you might look through the whole collection – and notice that they have generic ones like “#1 FRIEND” (i case you really don’t find your friend’s name), and, sometimes, generic ones in Spanish.
Zuse Z1 at the Deutsches Technikmuseum
My last blog post showed the Zuse Z3 (1939-1941), the world’s first working digital Turing-complete computer. Let’s go back two more steps: The Zuse Z1 (1936-1938) shared its design with the Z3: It read its program from punched film and used floating point as its internal representation of numbers. But since it was all mechanical, it never worked reliably.
Zuse Z3 at the Deutsches Museum
The Z3 by Konrad Zuse was the world’s first working digital Turing-complete computer. It did floating point arithmetic, had two registers accessible to the programmer, was microcoded, and clocked at about 5 Hz.

Amiga & Supergrips
This article is in German, since it is about the German TV show “Supergrips” and how the scoreboard was implemented.

Copland D9 Booting
Click on the image for a video of Copland D9 (the first developer release; the second one being D11E4), booting a bit, then hanging. It is running on a Power Macintosh 6100.
What Operating System Is This?
Unfortunately, I have not been able to successfully boot this up all the way on this machine – it hangs on this screen.
Inside Macintosh Volumes I, II, III (PDF)
Here are all three volumes of the original 1985 edition of Inside Macintosh as a searchable PDF:

"ROR" in Microsoft BASIC for 6502
If you disassemble any version of Microsoft BASIC for 6502, you’ll find this code in a function that normalizes the (simulated) floating point accumulator:
Building the Solaris Kernel in 73 Easy Steps
Everyone and their grandmother builds Linux kernels. Many people build BSD, and some brave men even compile the OS X kernel every now and then. Why not compile your own Solaris kernel for a change?
Bill Gates' Personal Easter Eggs in 8 Bit BASIC
If you type “WAIT6502,1” into a Commodore PET with BASIC V2 (1979), it will show the string “MICROSOFT!” at the top left corner of the screen. Legend has it Bill Gates himself inserted this easter egg “after he had had an argument with Commodore founder Jack Tramiel”, “just in case Commodore ever tried to claim that the code wasn’t from Microsoft”.
The Xbox 360 Security System and its Weaknesses
After the disaster of the original Xbox, Microsoft put a lot of effort in designing what is probably the most sophisticated consumer hardware security system to date. We present its design, its implementation, its weaknesses, how it was hacked, and how to do it better next time.
